SANITARY FLUID-DISPENSING APPARATUS.

Specification of Letters Patent.

Application filed July 8, 1911.

To all whom it may concern:

Be it known that I, WALTER S'IELLARD, a subject of the Netherlands, anda resident of the borough of Bronx, in the county of New York and Stateof New York, have invented certain new and useful Improvements inSanitary Fluid-Dispensing Apparatus, of which the following is aspecification.

This invention relates to a sanitary fluid dispensing apparatus, and isan improvement of my invention for which I filed an application on orabout September 10th, 1910, Serial No. 581,364.

The invention is characterized by sanitary means by which a fluid, milkand the like may be delivered in measured quantities from a can or tankwithout the fluid coming in contact with the operator. The can orreservoir is never open to the atmosphere while the fluid is takentherefrom, and said can or reservoir is contained in a closed vesselwhich may be packed with ice or other cooling agent, to maintain thefiuid at a proper temperature at small cost.

In the accompanying drawings, Figure 1 shows a front view of anapparatus exemplifying the invention, with a section taken on the line1, 1, of Fig. 2 and an axial vertical section of the lower portion ofthe invention, Fig. 2 represents a partial section of Fig. 1 on the line2, 2, Fig. 3 is a top plan view of the apparatus, Fig. 4 shows a partialsection of Fig. 2 on the line 4, 4, Fig. 5 represents an enlargedpartial section of the invention taken on a broken line as 5, 5 of Fig.6, Fig. 6 is a partial top plan view of Fig. 5, Fig. 7 represents apartial section of the upper portion of Fig. 5 on the line 7, 7, Fig. 8is a partial top plan view of Fig. 7, Fig. 9 shows an enlarged frontview of the tilting frame, and Fig. 10 represents a section of Fig. 9 onthe line 10, 10.

The invention is shown to comprise a receptacle 20 that has formedtherewith the tapered lower portion 21, the neck 22 with the opening 23,and the inclined discharging barrel 24 having threads 25 formed on theouter surface thereof. A measuring vessel 30 is supported in thedischarging barrel, a shoulder 31 on said vessel 30 bearing against theouter edge of the barrel 24. With the vessel 30 is formed thecylindrical spout 32, having the end wall 33 with the flange 34, thestop boss 35 and thedischarge opening 36 in the lower portion thereof. Aband 40 with notch 41, opening 42 and handle 45 encircles the spout 32,the said notch being in the path of the stop boss 35, and the opening 42being in the path of the opening 36. A secondary spout 43 extends belowthe opening 42 of the said band.

The ends of the band 40 are engaged by the clamping bolt 44. Themeasuring vessel 30 has formed therewith the rear wall 50 with theopening 51. A threaded clamping ring 52 engages the threads 25 and theshoulder 31 to securely clamp the measuring vessel 30 in place in thebarrel 24. Index lines 53 and 54 are formed on the walls of the vessel30 to measure the quantity of fluid therein.

A stopper designated generally by the numeral 55 has formed therewith athreaded barrel 56 that enters the opening 23 of the neck 22. A washer57 of pliable material, preferably rubber, is located around the barrel56 between the shoulder of the stopper formed by said barrel and the topface of the neck 22. A similar washer 58 of pliable material surroundssaid barrel and bears up against the lower face of the neck 22. A washer59 of same hard material bears up against the pliable washer 58 and anut 60 engages the threaded barrel 56 and bears up against the washer59.

A pair of rectangular cavities like 62 are formed in the stopper 55 tosupport an adjustable tilting frame to be described. An adjustable stop63 with the stem 64, and slotted head 65 is in threaded engagement withsaid stopper. A square cavity 66 is formed ins-aid stopper for a stem tobe described.

In the upper portion of the stopper is secured a tubular guide 70 withan opening 71 in the lower portion thereof, and a cap 72 at its upperend. A guide sheave 73 is journaled at the upper end of the said tubularguide. A cross head 76 is located within the tubular guide and isshouldered at 77 for a dust sleeve 78 that has an opening 79 that canregister with the opening 71 in tubular guide 7 O. A button 80 extendsfrom the sleeve 78 so as to locate it in different positions. The crosshead 76 is tapered at its lower end as shown at 81. It has an axialsquare opening in which is located the s uare lifting rod 85 of thedipper to be described, said rod being clamped in place by means of thescrew 86. An eye bolt 87 fastened in the tubular guide 70 and hasextending" therefrom the handle 90, to which latterone endiof thechainor band 88 is fastened.

In the cavities62 are located the rectangu lar. stems 100 of the ovaltilting frame 101. Eachof'the stems have a pair of openings 102,103, forthe shanks 104 of the suspending screws105. Stop screws like 106 are inthreaded engagement with the stopper 55 and-extend'into the cavities 62,just over the ends of-the stems 100 when the latter are in their lowestposition. The tilting frame 101 is notched at 107 for a cleaning washer108 that encircles the lifting rod 85. The frame 101 is stepped at itssides as shown at 109 and said sides are connected by a cross bar 110.An adjustable tilting-bar 115 bears against the rear side of thetilting,

frame and has extending therefrom a threaded boss 116, which carries inthreaded engagement the screw 117, that extends through an opening inthe cross bar 110. A cap nut 118 engages said screw and bears againstthe top face of'the bar 110 to clamp the" tilting bar 115 in differentpositions. The lower portion-of the tiltingfralne supports the dipperwhen the latter is in proper position to discharge the fluid therefrom.

The; lifting rod 85 has extending there-v from the bail 120 with thestop band 121 at the lower. end thereof. The said rod is preferablyrectangular: in cross-section to pre vent it from turning. A dipper 125is suspended in the bail 120 by means of the trunnions 126. It has anose 127 and in the bottom on the inside of said dipper is hinged aravity swinging check valve 128. The

hiiige'rod130of the check valve hinge has the legs131, by means 'ofwhich it' is prevented from openlng to a greater angle than shown indotted lines in Fig. 2, sothat when it descends it will close bygravity. A- counterweight 133 is fastened tothe dipper 125. v g

The receptacle 20 is supported in the wooden'ring 135 having ataperedopening to'suit the lower portion 21 of said receptacle. Ametallic ring 186 is supported'on the said wooden ring.'Supportingbraces 187 extend from notches 138 in the stopper 55 and bearon the ring 136 to prevent any excessive weight on or tremors to betransmittedto the receptacle 20. A vessel 140 is shown with the ringcover 141 onwhich is located the metallic ring 136. Within the vessel140 is shown a reservoir or can 142 from which the fluid is to bedipped.

Vhen the dipper is at the lower end of itsstrokethe sleeve 89-is at theop of -its stroke, and by hearing on the handle 90 the said sleeve isbrought to its lowest position which raisesthe bail 120 with the screw117, and at the same time locating the I The band 40 may. be locateddipper 125. When the dippercomes inthe I path of'the tilting bar 115 itis tilted and its contents are discharged into the measuring vessel 30,in which thelines 53-or 54 indicate the quantity that enters therein.The amount of fluid that is tilted into the vessel 30 can be varied, bylocating the tiltilfgbar 115 in different positions by means of thetilting frame in proper position by inserting stems 100, so'as to causethe lower side of the nose of the dipper to always bear on the lowerportionof the tilting frame, and the upper edges of said nose to bearagainst the; lower edge of the tilting bar 115. This dis-. position ofparts also prevents any oscilla-' tion of the dipper while it" isdischarging the fluid so as to empty said dipper of they desiredquantity. The adjustable st'op' determines the upper positions ofthe baiw for discharging different quantities of the fluid from the dipper.To'adjust the stop 68 the operator registers the opening 79 of the dustsleeve with the opening 71 in the "tubular guide 70, after which thesleeve is turned 'to close said openings relatively to each other, topreventany'dust from entering the apparatus. Itwill be notedthat thedipper 125 reaches the bottom of the can same. The measuring vessel 30canbe'easily detached from the receptacle 20' so that the parts of theapparatus can be removed and cleaned. The washer 108 always keeps thelifting rod 85 free from any fluid'before it travels through thestopper55.

so that'the openings 86 and 42 register with each'other atany time, todrainthe spout'32'of any fluid that may remain therein after use. Thereceptacle 20 and'measuring vessel 30-" are preferably made of glass sothat the/interior thereof is in fullview of the operator;

By this means and the fact that the parts of the apparatus can be easily.taken apart,

secures among other things the sanitary fea ture of the invention. i iHaving described desire to secure by 1sz- 1. In a fluid dispensingapparatus the, combination of a receptacle,'a dipper slid-' ablysuspended therein, means to reciprocate, the dipper, a reservoir tiltingframe adjustably suspended in said apparatus in the path of the dipperto tilt" the latter and thereby discharge a. prede termined quantityof'fluid therefrom.
